International Organization for Standardization (ISO) was founded in 1947 and its headquarters are located in Geneva, Switzerland.

Step 2:  Reflect on Internet and Computer Networking Experiences

Take a moment to think about the internet today in relation to the organizations and technologies you have just researched. Then answer the following questions.

Questions:

  1. How do the internet standards allow for greater commerce? What potential problems could we have if we did not have the IEEE?

Each company would development its own protocols and products which may not work with equipment from other companies.

  1. What potential problems could we have if we did not have the W3C?

We would not have a “common” language on the internet to display information and communicate with each other.

  1. What can we learn from the example of the Wi-Fi Alliance with regard to the necessity of networking standards?

If equipment manufacturers follow the same standards/rules, it allows for interoperability and backward compatibility. This encourages competition, allows for consumer choices and encourages the manufacturers to create better products.
